usage of the --path option (and other valid ember test options) needs clarification

when I read the docs I thought that --path option is only valid with the `exam:iterate` command.

It was not easy for me to understand that `--path` is also valid with the `exam` command also. The readme has the below quote regarding the ember test inheritance.
> Using Ember Exam is fairly straightforward as it extends directly from the default Ember-CLI test command. So, by default, it will work exactly the same as ember test.

After running `yarn run ember exam --help`, valid options were more clear to me. But seeing the path option only for the `exam:iterate` mislead me initially. I believe that explicitly stating that all the other `ember test` options are also valid for `ember exam` on the docs site and/or README could be beneficial. When I visit the docs site and see the options section, I immediately think that these are the only valid CLI options, there is nothing more.
